Eloy's Seismic Design Category, explained

Eloy carries Seismic Design Category B under USGS's ASCE 7-16 model. Low seismic hazard. Code requires basic seismic detailing (bracing, connections) but no special structural system restrictions. Rank it against the rest of the country and Eloy sits at the 51th percentile for seismic hazard among 4,875 US cities.

How Eloy compares

USGS's underlying values for Eloy: 0.084g peak ground acceleration, 0.192g at short period, 0.068g at 1 second. Within Arizona alone, Eloy ranks 43 of 57 cities by seismic hazard - the 25th percentile in-state. Eloy has a population of about 19,199.

What a retrofit costs in Eloy

A full earthquake retrofit typically runs $5,000-$10,000 nationally (around $7,000 typical), driven mainly by house size and foundation type, not by Arizona specifically. California's Earthquake Brace + Bolt grant, which covers a large share of this cost, is a California-only program and does not apply in Arizona.

Insuring against this, not just retrofitting

A Eloy homeowner cannot buy a standalone earthquake policy in most cases - it is added to an existing homeowners policy as an endorsement, so the place to start is a regular home-insurance quote.

Where Eloy's figures come from

Eloy's Category B and every number above trace to USGS's own ASCE 7-16 Design Maps service - see the methodology guide. See the category explainer for what Category B does and doesn't tell you about Eloy.
